1970 Chevelle Body Number Plates ~ Kansas City, MO. (KAN)

It is known that in 1970 Kansas City coded trim tag style numbers
with an even 3rd digit for a V8 and an odd 3rd digit for an L6 so the
Fisher Body Style number is a valid resource to tell if the car was
a V8 or L6.

Various letters are found on the third line of the trim tag. These
include:

B or W: Reported to indicate the color of optional D88 hood and deck
stripes. These seem to begin appearing in February.
L: Probably the most controversial is the letter L found on Malibu series
Chevelles. It's strongly believed this letter L indicates external SS396
or SS454 trim but this has NOT been confirmed by any direct knowledge
or GM documentation. One known SS396 optioned Malibu has been reported
(but not verified) without this letter L. While using this letter
as a way to determine if your 1970 Chevelle is a true SS396 or SS454
or not is up to you, there is no 100% guarantee but there is strong
evidence that it does.
X: Found on 13369 Standard 4-Door Sedan.
Z: Found on 13437 Standard sport coupe and 13480 El Camino.

The 5-digit number following the body date is purported to decode
to the xxxth car on the xxx work day of the week such as 05361 would
decode to the 536th car on the 1st work day of the week. Whether this
is true or not isn't known.
